🚦 Efficiency Ratio & Performance

Frizzlife

Below, we’ve shared the efficiency ratio and performance for each Frizzlife model:

  • The Frizzlife RO-K3 Tank-Based RO System uses a 6-layer filter cartridge that combines a 2-in-1 composite pre-filter, a 0.0001-micron RO membrane, and a post-carbon alkalizing filter. It has a 100 GPD flow rate and a 1:1 pure-to-wastewater ratio.
  • The Frizzlife PD600-TAM3 Tankless RO System With Alkaline Remineralization uses 7-stage deep filtration that combines a pleated sediment filter with an RO membrane, an ACF1 and ACF2 media, a carbon block filter, a remineralizing stage, and a weak alkaline filter. It has a 600 GPD flow rate and an efficiency ratio of 1.5:1, meaning that 1.5 gallons of pure water are produced for every 1 gallon wasted.
  • The Frizzlife PX500 – 500 GPD combines three separate stages of filtration with 7-8 total filter layers (depending on whether or not you buy the filter with remineralization), including a PPC layer, an RO membrane layer, a polishing layer, and a remineralization layer (optional). The filter has a 500 GPD flow rate and a 1.5:1 efficiency ratio.
  • The Frizzlife PD400 and PD500 use two filters that combine 5 stages of filtration, including a pleated sediment filter, high-grade ACF1 and ACF2 media, an RO membrane, and a polishing filter stage. You can buy the system with400 GPD and 500 GPD flow rates, and both have an efficiency ratio of 1.5:1.
  • The Frizzlife PD800-TAM4 and PD1000-TAM4 are Frizzlife’s superior under-sink reverse osmosis offerings, combining 7 stages of filtration in two filters, including a pleated sediment filter, high-grade ACF1 and ACF2 media, an RO membrane, an acid-washed coconut carbon block filter, and an alkaline and remineralization stage. There are two unit configurations available, with 800 GPD and 1,000 GPD flow rates and an efficiency ratio of 2:1, meaning that only 1 gallon is wasted for every 2 gallons produced.

📌 Is there anything else worth knowing about the Frizzlife under-sink RO filters’ performance? None of the systems are currently NSF certified, although some other Frizzlife products are (more on that later), and none currently offer a better efficiency ratio than 2:1.

💬 Customer Reviews & Complaints

Frizzlife

The average rating for Frizzlife reverse osmosis systems on Amazon is between 4.2 and 4.6 stars (out of 5).

Generally, customers were pleased because:

  • The installation instructions are easy to follow
  • They enjoyed the taste of their filtered water
  • They noticed significantly reduced TDS (one person reported down to 00 – 01 PPM after using the system)

A few customer complaints were:

  • Flow rate – some customers said that their system didn’t seem as fast as advertised
  • Poor fridge compatibility – several reviewers noted that the 600 GPD systems and those with lower flow rates reduce water flow and ice-making speed by half in refrigerators

Waterdrop

Waterdrop is another highly-rated brand on Amazon, with average reviews of 4.6-4.8 stars for its RO under-sink water filters.

Customers were happy with:

  • The option to buy an under-sink RO system with an NSF certification (for the G3)
  • The great taste of the filtered tap water
  • The easy installation and simple filter changes

A few complaints we picked up on were:

  • Some customers said that the water pressure was low even after installing a booster pump
  • A few people questioned the accuracy of the TDS reading, and one person received slightly different TDS results from a lab test than the unit displayed

☑️ Pros and Cons

Frizzlife Pros

  • We love how much choice you get with different units. There’s a system for every budget and every preferred flow rate, from 100 GPD (which is still better than the average 50 GPD for under-sink RO) to a massive 1,000 GPD.
  • You only have to pay a bit more money to enjoy the smart features that Frizzlife is known for, like a smart LED display with a built-in TDS system.
  • The RO filtration process in all the Frizzlife water filter systems (regardless of price) is thorough and incorporates more stages than a standard RO system. Many of the systems also come with an alkalizing filter that adds healthy minerals back into filtered drinking water.
  • All bar one Frizzlife under-sink RO systems are tankless, so they’re more compact and space-saving.

Frizzlife Cons

  • Having so much choice between products can be overwhelming. On the RO product page, Frizzlife doesn’t make a clear distinction between some of the units, so you have to really dig into each product and do your own research to understand the differences.
  • We can’t find any information to suggest that any Frizzlife water filter RO systems are NSF certified.

Waterdrop Pros

  • You get even more choice with Waterdrop (7 RO under-sink water filters vs Frizzlife’s 5). This includes a hot water RO dispenser.
  • Waterdrop has a cheaper option for small budgets compared to Frizzlife. The H7 costs just $150.
  • Again, you get excellent purification from Waterdrop’s RO under-sink water filter models, and the G3 even has NSF certifications for its performance.
  • Like Frizzlife, Waterdrop mostly sells tankless RO systems, which take up less space under your kitchen sink.

Waterdrop Cons

  • Waterdrop’s most expensive RO under-sink filter system is costlier than Frizzlife’s, but it’s only 800 GPD, while Frizzlife’s is 1,000 GPD.
  • Similarly to Frizzlife, Waterdrop doesn’t make a super clear distinction between some of its RO under-sink water filters, which could be confusing to new customers with limited reverse osmosis knowledge.

Filter cartridge of the frizzlife kf99

Waterdrop

Here’s what we know about the filter media used in Waterdrop’s under-sink water filter systems:

  • The Waterdrop TST-UF, TSU-W and TSU-B Ultrafiltration Under Sink Water Filter Systems use 3 filter stages with 6 layers of filtration. The filter cartridges are a PP cotton filter, a UF filter, and a CT filter.
  • The Waterdrop TSC-W Under Sink Filtration System Integrated Dual Carbon is a non-ultrafiltration system. It uses the same PP and CT filter as the Waterdrop ultrafiltration systems, but swaps the UF filter for a CS (carbon) filter.
  • Waterdrop WD-U8-FC Under Sink Single Stage Water Filter uses a single filter cartridge that combines activated carbon block media with a PP cotton layer.
  • The Waterdrop WD-UA Direct Connect Under Sink Water Filter is another single-cartridge filter that combines activated carbon block media with a polyester membrane and KDF media.
  • The Waterdrop WD-UA-UF Direct Connect Under Sink Ultrafiltration Water Filter uses a single advanced ultrafiltration membrane.

🧫 Contaminants Removed

Frizzlife

The different Frizzlife under-sink systems remove their own unique sets of contaminants, but they have one thing in common: they’re all certified to NSF Standards 53 and 42 for the reduction of chlorine, lead, and more.

There’s a crossover between the filter media used in most systems, which means most remove a similar set of contaminants.

Some of the contaminants removed by the Frizzlife systems are:

  • Chlorine
  • Chloramine
  • Lead
  • Fluoride
  • Heavy metals
  • Volatile organic compounds
  • Bad tastes and odors

Waterdrop

Waterdrop offers both standard filters (such as sediment filters, activated carbon filters. etc.) and ultrafiltration filters in its under-sink systems.

Some of the contaminants removed by the Waterdrop systems are:

  • Sediment
  • Rust
  • Suspended impurities
  • Chlorine taste and odor
  • Heavy metals
  • Fluoride
  • Scale
  • Hydrogen sulfide

Check the filer you’re interested in to see exactly what it removes.

🚦 Performance Comparison

Frizzlife

The performance of a Frizzlife system is linked to the system size, filter materials, and complexity.

In terms of contaminant removal, Frizzlife’s systems remove the majority of the impurities you’re most likely to be concerned about in your drinking water. This includes contaminants like fluoride, but make sure to check before you buy, because not all Frizzlife under-sink units remove this impurity.

As for flow rate, most systems rate between 1.4 and 2.0 GPM, which is great – 2.0 GPM is the maximum flow rate recommended for kitchen sinks without water filters. The ultrafiltration system has a slightly slower flow rate of 1.18 GPM, but this is still faster than most similar models on the market.

📌 In all, Frizzlife’s under-sink offerings offer a basic but reliable performance. It’s great to see that most systems use an NSF certified filter to give you that extra bit of reassurance that they’re capable of living up to the manufacturer’s performance claims.

Filter cartridges of the frizzlife gx99

Waterdrop

Again, the exact filter size, complexity, and materials used in a Waterdrop under-sink filter determine its performance abilities.

Generally, Waterdrop offers good contaminant removal. You’d expect any filter to remove chlorine at the very least, and it’s good to see that Waterdrop’s filters go beyond this – some even remove fluoride and arsenic. And if you want to remove more contaminants but don’t want to invest in reverse osmosis, remember, you can always upgrade to one of Waterdrop’s under-sink ultrafiltration systems.

The flow rate of Waterdrop’s systems is a bit lower than Frizzlife’s – about 0.75 GPM for the single-stage systems and 1 GPM for the multi-stage systems. You might notice a dip in your water pressure after installing a Waterdrop system at your kitchen sink.

📌 The performance stats for Waterdrop’s under-sink water filtration systems are good, and again, it’s reassuring to see that a few (although not as many) of its systems are NSF certified to Standard 42 (for chlorine removal) and 372 (for lead-free materials), including the single-stage Direct Connect Water Filter, the Inline Water Filter for refrigerators, and the 3-stage Waterdrop TSA.

Waterdrop TST-UF$190
Waterdrop TSU-W $300
Waterdrop TSC-W$285
Waterdrop Under Sink Single$65
Waterdrop Direct Connect$70 or $90 (stainless steel model)
Waterdrop Direct Connect Ultrafiltration$61 or $72 (with faucet)
Waterdrop Undersink Inline$60
Waterdrop Undersink Inline Ultrafiltration $70
Waterdrop TSA$130 or $140 (with faucet)

Both brands are similarly priced in this area. There’s only a $5-20 difference in cost between most products, so it would be difficult to choose a favorite based on price alone. Waterdrop has a few more higher-priced options for under-sink ultrafiltration.

📆 Filter Lifespan & Replacement Costs

Frizzlife

Replacement filters for the Frizzlife under-sink systems cost $20-$55 on average, depending on the filter type and the number of filters in the package. On average, the filters last 6-12 months, but some (such as the filter for the MV99) have a 2-3-year maximum lifespan (depending on your water quality and usage).

Waterdrop

Again, different Waterdrop filter replacement cartridges have different lifespans, but the average lifespan is from 6 months (2,000 gallons) to 24 months (8,000 gallons). The cost of a filter replacement for a single-stage filter is generally higher per filter than the cost per filter for a multi-stage system. Average replacement filter cost: $25-$40 per filter. You can also buy multi-packs of filters to save money.

☑️ Pros and Cons

Frizzlife Pros

  • We like that Frizzlife offers numerous options, including single-stage and multi-stage systems, and ultrafiltration systems.
  • Most systems are NSF certified to Standards 42 and 53, so they offer guaranteed good performance.
  • Connecting the filters to an under-sink water line is easy thanks to the quick-connect fittings.

Frizzlife Cons

  • As we mentioned with the RO reviews, we think Frizzlife offers far too many models and configurations for its under-sink units.
  • The manufacturer should also be a lot clearer on the exact differences between its similar filters so that customers know instantly which product is right for them.

Waterdrop Pros

  • Waterdrop offers more ultrafiltration systems than Frizzlife, so go for this brand if you’re specifically looking for this type of filtration.
  • We appreciate that you can upgrade a number of Waterdrop under-sink systems to stainless steel models for improved durability and leak-proofing.
  • Waterdrop’s systems are also super easy to connect, with pre-assembled filter housings and quick-connect fittings.

Waterdrop Cons

  • Waterdrop also offers too many configurations for its under-sink models, and it isn’t obvious at a glance how certain products differ from one another (apart from price).
  • Most of Waterdrop’s under-sink filters (with the exception of 3 models) aren’t NSF certified.

🍶 Water Filter Pitchers

Frizzlife

Frizzlife is pretty new to the gravity filtration market and currently sells a single water filter pitcher:

  • The Frizzlife FP40 10-Cup Water Filter Pitcher

Waterdrop

Waterdrop has a few more pitcher options:

  • The Waterdrop Elfin 5-Cup Pitcher Water Filter
  • The Waterdrop Lucid 10-cup Water Pitcher Filter
  • The Waterdrop Chubby Pitcher Water Filter
  • The Waterdrop Pitcher Water Filter With High Capacity
  • The Waterdrop Zero TDS 10-Cup Pitcher Water Filter

📌 All of Waterdrop’s pitcher filters use the same NSF-certified activated carbon filter, apart from the Waterdrop Zero TDS Pitcher, which uses several filter media to reduce TDS to 0.

Waterdrop also offers a couple of water dispensers that use the same activated carbon filter as the pitchers.

💡 Media Comparison

Frizzlife

Frizzlife water filter pitchers use a single filter cartridge that combines activated carbon, a PP layer and a “special resin” (the manufacturer’s words, probably ion exchange) to reduce an impressive range of contaminants.

This is a pretty common media combination for water filter pitchers. Activated carbon works best with a slow flow rate as it gives water a longer contact time with the media. As a tried and tested water filter media, activated carbon is a reliable choice from Frizzlife. The only disappointment is that the filters don’t appear to have an NSF certification or third-party testing.

Frizzlife fp40 cartridge

Waterdrop

In this review, we’ll be comparing the media in the Waterdrop carbon filter (not the zero TDS filter) since this is most comparable to the Frizzlife filter.

Again, this filter doesn’t stand out as one of the best we’ve seen for contaminant removal, but it’s still well-designed, with an NSF certification to support the manufacturer’s performance claims.

Waterdrop says that the pitcher filter uses “multi-stage technology”, including two non-woven fabric stages, an ion exchange resin, and coconut shell activated carbon media. Both ion exchange and activated carbon are reliable, effective choices that most people have come to expect in a water pitcher.

🧫 Contaminants Removed

Frizzlife

According to Frizzlife, the 3-in-1 filter in the water pitcher can remove the following contaminants:

  • Chlorine
  • Lead
  • Mercury
  • Copper
  • Aluminum
  • Other heavy metals
  • Fluoride
  • Sediment
  • Poor tastes and odors

⚠️ The manufacturer claims that the filter can “soften water”, while also claiming that the filter retains healthy calcium and magnesium minerals – two things that can’t happen concurrently. No water filter can soften water (you need a water softener for that) and there are no benefits of drinking soft water anyway, so you should disregard that claim.

Waterdrop

The Waterdrop filter is tested and certified to remove tap water contaminants including:

  • Chlorine (97.4%)
  • Arsenic
  • Fluoride
  • Heavy metals
  • Limescale (may control scale but doesn’t remove hard minerals)
  • Heavy metals
  • Poor tastes and odors

Waterdrop doesn’t share any test results online, so we don’t have a definite full list of the contaminants removed.

🚦 Performance Comparison

Frizzlife

There are a few performance factors we consider when reviewing water pitcher filters: filtration thoroughness, speed, and longevity.

The Frizzlife FP40 ticks a lot of boxes when it comes to performance, reducing even some of the most difficult-to-remove contaminants in tap water, like fluoride. With that said, we’ve seen some much more capable filter pitchers that remove hundreds of contaminants from water, so this Frizzlife pitcher isn’t on our list of top recommended products by any means.

As for filtration speed, you can actually adjust the flow rate yourself by turning the flow regulator at the bottom of the cartridge (an unusual feature that we haven’t seen much of before). That means you can get fast access to water if you want it, but we’d always recommend keeping the flow rate as slow as possible for the most thorough contaminant removal.

The filters last about 2 months, which is pretty average for a water filter pitcher. You wouldn’t expect the filter to last much longer than this if it was doing its job – the media naturally becomes clogged with contaminants over time.

As we mentioned earlier, it’s a little disappointing that Frizzlife doesn’t have any NSF certification for contaminant removal to back up the manufacturer’s performance claims.

Frizzlife fp40 performance

Waterdrop

Waterdrop is superior to Frizzlife in almost every performance category with its water filter pitcher.

Again, the Waterdrop filter doesn’t remove hundreds of contaminants like some pitchers, but it tackles many of the contaminants commonly found in city water supplies, including tricky-to-remove arsenic and fluoride.

The rated flow for this filter is 0.5 GPM, which is slower than a faucet flow rate (around 2 GPM), but decent for a pitcher system. There’s no option to adjust the filter speed, but we think that’s a pretty pointless feature anyway. Best to leave the filter to treat your water at a slower pace, since this removes the most contaminants by extending water’s contact time with the filter media.

The filter life of a Waterdrop pitcher filter is 200 gallons – that’s 4 times the lifespan of the Frizzlife water filter, although this apparently only gives you an extra month of use (3 months versus 2 months).

And finally, it’s good to see that the carbon filters in the Waterdrop pitchers are all officially tested and certified to NSF Standard 42, for the reduction of chlorine, taste, and odor, and NSF 372, for lead-free material.

💲 Models & Upfront Cost

Frizzlife

Frizzlife’s single 10-cup water filter pitcher model costs just under $30. That’s cheap compared to some of the best filter pitchers on the market, which cost closer to $100 but remove far more contaminants.

Waterdrop

We’ve listed the currently available Waterdrop pitcher models and their costs below.

ModelCost
Waterdrop Elfin$20
Waterdrop Lucid$26
Waterdrop Chubby$29
Waterdrop Pitcher$27
Waterdrop Zero$29

Waterdrop and Frizzlifeare very competitively priced in this category, but Waterdrop has a few more choices for smaller budgets.

📆 Filter Lifespan & Replacement Costs

Frizzlife

You can buy a pack of 2 replacement filters on the Frizzlife website for about $16. Again, that’s a great deal, and about right for a filter that removes a handful of contaminants and has a 2-month or 50-gallon lifespan.

Waterdrop

A 2-pack of replacement Waterdrop filters is about $30 – so around twice the cost of Frizzlife filters. Since Waterdrop’s filters are NSF certified and have a longer filter life of 200 gallons/3 months, we think this price is justified. You’ll only have to buy replacement filters about 4 times a year, versus Frizzlife’s 6 times a year.

💬 Customer Reviews & Complaints

Frizzlife

Frizzlife’s pitcher and replacement filters have 4.3-4.5 star overall ratings on average, suggesting that Frizzlife isn’t quite as popular in this area as in the under-sink filter niche.

Customers praise the Frizzlife filter pitcher for:

  • Making a noticeable improvement to the taste of drinking water
  • Being easy to assemble and use
  • Having an attractive, modern design

Some customers complained that:

  • The pitcher doesn’t hold as much water as expected
  • It takes a long time for water to flow through the filter
Frizzlife fp40 cartridge takes time

Waterdrop

Waterdrop has an average star rating of 4.6 on Amazon for its pitcher filter products, and the Waterdrop Chubby pitcher is currently an Amazon’s Choice model product thanks to its good reviews and the manufacturer’s quick shipping.

Customers were happy with the pitcher because:

  • The filter design is attractive and sturdy (no leaks or recontamination of filtered water)
  • The pitcher is fast to filter a batch of water, and you don’t have to open the lid to top up the water
  • Filtered water tastes great

Customers weren’t so pleased that:

  • The pitcher gets heavy when it’s full
  • The lid falls off when you pour at too much of an angle

☑️ Pros and Cons

Frizzlife Pros

  • The Frizzlife FP40 is cheaper than most other pitchers and gravity countertop water filters.
  • The filter should improve the taste of your water, and it’s impressive that some of the more challenging contaminants are removed, like fluoride.
  • Assembly and maintenance are easy.

Frizzlife Cons

  • The filter only removes a handful of contaminants, so it won’t massively improve your water quality.
  • The water flow rate slows significantly after just a couple of weeks (some customers reported it taking hours to filter a single batch of water).

Waterdrop Pros

  • The activated carbon filter used in most of Waterdrop’s pitcher models is NSF-certified – a reassuring sign of quality performance.
  • You get more options with Waterdrop compared to Frizzlife, including a choice between two filters and several pitcher sizes and colors, including a couple of bigger dispensers.
  • The filter’s 200-gallon lifespan is 4 times the Frizzlife filter’s 50-gallon lifespan.

Waterdrop Cons

  • The lid design on a number of the pitchers isn’t secure, which means it falls off if you tilt the pitcher at too much of an angle when pouring.
  • The filter might not last 2 months if your water quality is poor.

🥇Frizzlife Vs Waterdrop: Who Wins?

So, in this Frizzlife vs Waterdrop comparison, which brand do we think is best?

Frizzlife and Waterdrop are best known for their reverse osmosis under-sink filtration systems, and our winner in this category is Waterdrop.

It’s a close call, since Frizzlife has a few selling points that Waterdrop doesn’t, including a 1,000 GPD system. Both brands offer very similar products, but Waterdrop offers a larger range (including a hot water dispensing RO system – the very first of its kind) and also offers an NSF certified system for customers who care about third-party testing.

What about their non-RO under-sink filtration systems?

Frizzlife has more offerings than Waterdrop, including more NSF certified systems, and most of its systems have a faster flow rate. However, Waterdrop offers more ultrafiltration systems (including an inline ultrafiltration system for refrigerators) and is very competitively priced, so you can’t go wrong with either brand in this category.

Finally, let’s summarize Frizzlife vs Waterdrop water filter pitchers.

Waterdrop is the clear winner here, with two different filter choices (including an NSF certified carbon filter) and multiple pitcher sizes, colors, and designs to choose from. Plus, Waterdrop’s carbon filter (the most comparable to the Frizzlife filter) is much longer lasting, with a 200-gallon lifespan compared to the Frizzlife filter’s 50-gallon lifespan.

In all, we think both brands are good, especially when it comes to under-sink filters and reverse osmosis filters, but Waterdrop comes out just on top.

However, in these categories, you should enjoy a filtration experience that’s significantly better than what’s offered by most other manufacturers, regardless of which brand you choose.
